Rekordbox OSX Wireless LAN via Airport Express

After some troubleshooting, I was able to get my XDJ-RX linked wirelessly to Rekordbox on my MacBook Pro (OS X 10.10.15) via an Airport Express (2nd Gen). Since I don't have direct access to a modem (I syphon internet from the bar downstairs in my apartment building), I configured the Airport Express to create a wireless network, put it in 'Bridge Mode', and connect to that network on my laptop. Putting the router in Bridge Mode was key in getting this to work with Rekordbox. This works flawlessly and I'm able to browse my entire collection via the XDJ, drag n drop tracks on my laptop, and have experienced no latency issues or hiccups.

The only problem is I'd like to be connected to the internet at the same time. Wondering if anyone else has a similar setup (with an Airport Express and no direct access to a modem), and was able to configure it to extend or join an existing network while also being able to link wirelessly with Rekordbox?

Hoping this info is helpful for other Mac users as well :)
